Transmission control method and transmission control device

Abstract

A transmission control method executed by a computer. The method includes transmitting first image information that is displayed on a head mounted display to a terminal, extracting, when designation information for designating a first range included in the first image information is received from the terminal, second image information corresponding to the first range from the first image information, and transmitting the second image information to the terminal.

What is claimed is: 
     
         1 . A transmission control method executed by a computer, the method comprising:
 transmitting first image information that is displayed on a head mounted display to a terminal;   extracting, when designation information for designating a first range included in the first image information is received from the terminal, second image information corresponding to the first range from the first image information; and   transmitting the second image information to the terminal.   
     
     
         2 . The transmission control method according to  claim 1 , wherein the transmitting the first image information to the terminal is processing of reducing resolution of the first image information and transmitting the reduced first image information to the display terminal. 
     
     
         3 . The transmission control method according to  claim 2 , wherein the transmitting the second image information to the terminal is processing of transmitting the second image information to the terminal without reducing resolution of the second image information. 
     
     
         4 . The transmission control method according to  claim 1 , wherein the first range is designated by a certain operation in a display unit of the terminal that has displayed the first image information. 
     
     
         5 . The transmission control method according to  claim 4 , wherein the certain operation is an operation of magnification or reduction. 
     
     
         6 . The transmission control method according to  claim 1 , wherein the designation information is information indicating a first ratio that indicates scaling of an image. 
     
     
         7 . The transmission control method according to  claim 6 , wherein the first range is determined based on the first ratio and a size of first image information. 
     
     
         8 . The transmission control method according to  claim 1 , wherein, in the extracting, when a size of the second image information exceeds a specific image size, the size of the second image information is reduced to the specific image size or less. 
     
     
         9 . A transmission control device comprising:
 a memory; and   a processor coupled to the memory and the processor configured to:   execute first transmission of first image information that is displayed on a head mounted display to a terminal,   extract, when designation information for designating a first range included in the first image information is received from the terminal, second image information corresponding to the first range from the first image information, and   execute second transmission of the second image information to the terminal.   
     
     
         10 . The transmission control device according to  claim 9 , wherein the first transmission is processing of reducing resolution of the first image information and transmitting the reduced first image information to the display terminal. 
     
     
         11 . The transmission control device according to  claim 10 , wherein the second transmission is processing of transmitting the second image information to the terminal without reducing resolution of the second image information. 
     
     
         12 . The transmission control device according to  claim 9 , wherein the first range is designated by a certain operation in a display unit of the terminal that has displayed the first image information. 
     
     
         13 . A non-transitory computer-readable recording medium storing a transmission control program that causes a computer to execute a process comprising:
 transmitting first image information that is displayed on a head mounted display to a terminal;   extracting, when designation information for designating a first range included in the first image information is received from the terminal, second image information corresponding to the first range from the first image information; and   transmitting the second image information to the terminal.
